Hva betyr feilkoden?
The high voltage generator control module (IGM) communicates with the other control modules over the CAN bus. The code means that the signal configuration for HS CAN does not match, or that there is interference on the CAN. The fault is only checked once the test has started at ignition on.
Mulige årsaker
- Faulty configuration
- Incorrect configuration ID; the module is meant for another car, for example a used module with different software or hardware
- Software fault in the IGM
- Software error in the restraint system control module (SRS)
Hva du kan gjøre
- 1Read out, clear the code, start the car and see whether it comes back
- 2If any control module has recently been replaced, check that it is intended for this particular car
- 3Have a workshop with diagnostic equipment reprogram the control module and download the latest software
- 4The high voltage system may only be handled by a workshop; do not work on it yourself
Symptomer du kan merke5
- Warning symbol and text message in the display
- Warning about power supply problems from the alternator and charge regulator
- Charging of the high voltage battery while driving is absent, reduced or not working correctly
- High voltage battery is discharged or charges poorly
- HYBRID drive mode: the combustion engine is active all the time or too often
Hva feilen kan påvirke3
- The control module switches itself off (bus-off) and stays off until the power supply has been disconnected
- The high voltage battery cannot be charged by the combustion engine
- When the power supply is reconnected, the control module tries to communicate again
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
